GEORGE SYLVESTER TIFFANY, OF TECUMSEH, MICHIGAN.

CRUSHER FOR CLAY, CLODS, 84,0.

EiEEiGIE'lCATION forming part of Letters Patent No. 307,820, dated November 11, 1884.

Application filed May L 1854. (No model.)

Zb-aZZ whom, it may concern.-

Be it known that I, GEORGE S. TIFFANY, a citizen of the United States of America, residing at Tecumseh, inthe county ofLenawee and State of Michigan, have invented a certain new and useful Improvement in Crushers, of which the following is a specification.

My invention relates to improvements in machines for crushing material preparatory to submitting the material to further disintegra tion, and has special relation to the prepara' tion of clay, clods, &c., for the action of the grinding or pulverizing machinery.

The object ofmy invention is to provide a machine to take and crush hard and unyielding clods of clay and such foreign substances as maybe mixed with it into such comminuted state that it may be readily, freely, and altogether taken in by the grinding or pulverizing machinery.

My invention therefore consists in the novel construction and combination of parts, as will be hereinafter more fully described, and specifically stated.

In the accompanying drawings, fully illustrating my improved machine and forming a part of this specification, Figure 1 is a perspective of the complete machine. Fig. 2 is a plan view thereof. Fig. 3 is a vertical sectional view taken through the line 00 a: of Fig. 2, and Fig. 4 is a detail view of one of the crusher bars or blades, with a transverse sectional View showing the shape of the blades in cross-section.

The letter A represents the frame 'of the machine, made up of the side pieces, a a, cast solid with the top and bottom cross-pieces,b I), intermediate cross-pieces, c c, and vertical standards (1 d, formed with journal'bearings 6. These side pieces of the frame are secured together at the top at each end by strong tieplates f, substantially as shown, and the frame of the machine is further formed or provided with journal-bearings g for the crank-shaft, and h for the stationary crusher-s, and t forthe driving-shaft.

The letter B represents the driving-shaft, journaled in or to the hind standards of the frame in bearings 43. This shaft is provided with a belt-pulley 011 one end, and on the other end is fixed the gear-wheel 7c, the latter of which meshes with the larger gear-wheel,0,

on the shaft- D, working in bearings g on the frame. This shaft D has fixed to it the crankarm Z, the free end of which has attached thereto one end of the connectingrod in. The other end of said rod is fitted to the shaft E, and to the arm of the gear-wheel C is fixed a wrist pin, Z, arranged coincident with the crank-arm Z, and attached to this wrist-pin Z is the connecting-rod m, the other end of which is connected to the shaft E, substantially as shown in Fig. 2 of the drawings.

It is apparent that instead of attaching the connectingrod m to a pin on thevgear-wheel O, the shaft D may be extended and a duplicate crank-arm be fixed thereto, to which the connecting-rod can be attached.

The letters F and F represent a number of blades or bars, the lower ends of which are arranged in alternate succession on the shaft a, resting in fixed bearings e in the vertical standards of the frame. The upper ends of the bars F are arranged on the shaft q, held in bearings h on the frame, and secured in place by any proper means. These bars or blades F are set to incline from their base rearward to their top. The bars or blades F have their upper ends arranged on the shaft E, which is connected to the crank-arms by the connecting-bars m and at, substantially as shown.

In Fig. 4. is shown the particular form of one of the bladesin full, and also the shape in cross-section, the latter showing the form as taken through the line y y of the remaining detail of the figure. It will be seen that the face or operating-edge 1 is square, and that the blade extends of uniform thickness for a short distance rearward of the face and then is made somewhat wedge shaped. This particular construction gives sufficiently broad contacting-face surface for all purposes and widens the distances between the backs of the blades, so that the material forced through the interstices shall not stick between the blades and clog the machine. The lower ends of the blades are formed with solid circular disks 2, and the perpendicularity of each blade is maintained by forming the upper ends with a solid collar, 3, on each side.

Secured to each side of the frame, and ar ranged to cover the space between the center blades,are triangular-shaped plates G. These serve to prevent the material submitted to the machine from dropping out or from being forced out at the sides of the grates or basket. The bars or blades may be secured against lateral displacement by arranging on the respective shafts sleeves or washers with setscrews to set them in any desired position. In arranging the bars it is intended that the crank-connection shall move the reciprocating blades so that their faces for the whole length shall operate as crushing-surfaces, and so that by passing into the interstices of the stationary bars they shall serve to push out and free the material from between both series.

The operation is as follows: The power being applied to the driving-shaft, motion is communicated to the large gear-wheel, which turns the cranks and gives a reciprocating motion through the connecting-rods to the outer set of bars, which in their inward movement press the material in the machine against the stationary bars and effect the disintegration of whatever may oppose the pressure.

\Vhat I claim, and desire to secure by Letters Patent, is

l. A blade or bar for a crusher formed with a fiat contacting face and wedge-shaped body in cross section, and provided with apertures in each end to receive sustaining-shafts, substantially as described.

2. The stationary bars or blades having their upper and lower ends arranged on fixed shafts, in combination with the movable bars or blades having their lower ends arranged 011 a fixed shaft and interposed in alternate succession between the stationary bars or blades on the same'fixed shaft, and their upper ends arranged on a movable shaft connected to means for reciprocating it, substantially as described.

3. A series of fixed bars or blades having their upper ends arranged on a fixed shaft, and a series of movable bars or blades having their upper ends arranged on a movable shaft, and both series having their lower ends arranged on the same fixed shaft in alternate succession, in combination with the side plates arranged and secured to cover the space between the outer blades, substantially as described.

4. A series of fixed bars or blades having their upper ends arranged on a fixed shaft, and a series of movable bars or blades having their upper ends arranged on a movable shaft, and both series having their lower ends arranged on the same fixed shaft in alternate succession, in combination with the crankrods, the shaft having a gear-wheel fixed thereon, and provided with means, substantially as described,for reciprocating the crankrods and driving-shaft,with gear-wheel meshing with the gear-wheel on the crank-shaft, substantially as described.

5. A series of fixed bars or bladeshaving their upper ends arranged on a fixed shaft, and a series of movable bars or blades having their upper ends arranged on a movable shaft, and both series having their lower ends arranged on the same fixed shaft in alternate succession, in combination with the frame provided with side plates arranged to cover the space between the outer opposite blades, the crank-rods, shaft having a gear-wheel mounted therein, and provided with means, substantially as described, for reciprocating the crank-rods and driving-shaft, with gearwheel meshing with the gear-wheel on the crank-shaft, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two attesting witnesses.

GEO. SYLVESTER TIFFANY.
